Is the Limited user account that is causing the problem a new account you created or you administrators account changed to a limited user account?
If it is the former then i suggest you
1/ delete the limited user account you are having trouble with.
2/ Change your admistrators account that is working ok to a limited user account.
3/ Create a new administrators account so as to be able to install/uninstall programs.
And see if that works ok
